My hosting provider required php 7.2 going forward, so had to update a few concrete5 legacy sites. 2 failed the update, and not having any luck trying to resolve I decided to simply restore from the hosting backup both the site and database. However now I am just getting server500 errors.

I could do with some help trying to resolve, as I have got to the end of where my limited skills will take with resolving.

Any advice anyone can offer will be greatly appreciated
